Question 15.4. Which of the following statements regarding catheter complications is

NOT true?

A. Infection is the most common cause of catheter loss.

B. Tunneled catheters with externalized hubs are less likely to develop

infection than implanted subcutaneous devices.

C. The most common pathogen in catheter-associated bacteremia is a

coagulase-negative staphylococci.

D. Catheter salvage is possible with several weeks of antibiotics.

Question 15.5. Which of the following is an indication for infected catheter removal?

A. Inability to clear the infection with antibiotic therapy.

B. Continued signs and symptoms of bacteremia.

C. Recurrent infection after completion of a full course of antibiotics.

D. All the above.

Question 15.6. Regarding percutaneous ablation of pulmonary tumors, which is NOT

true?

A. Currently reserved for patients whose operative risk is too high.

B. Performed under conscious sedation.

C. Efficacy is based on size and location of the lesion.

D. Most common complication is pulmonary hemorrhage.

Question 15.7. Regarding percutaneous abdominal and pelvic biopsies, which is NOT

true?

A. Pneumothorax is a well-known potential complication of adrenal

biopsies.

B. Liver biopsies may need a core biopsy to distinguish well-

differentiated neoplasms from benign lesions.

C. Fewer complications are sustained from crossing the transverse colon

than the inferior vena cava (IVC) when performing pancreatic biop-

sies.

D. Pelvic percutaneous biopsies are the preferred technique when ovar-

ian cancer leads the differential diagnosis.

E. Pelvic sarcomas often require core biopsies.

Question 15.8. Regarding percutaneous gastrostomy tubes, which is NOT true?

A. Requires less sedation than endoscopy-placed feeding tube.

B. May be placed for feeding or decompression.

C. Contraindicated in patients with prior gastrectomy.
